являться/служить + Instrumental
Formal Predicate Instrumental
In formal Russian, instead of omitting the verb 'to be' or using simple verbs, writers use являться (to be/constitute) and служить (to serve as) followed by the Instrumental case.
How It Works
This pattern is a hallmark of канцелярит (bureaucratic style) and scientific prose. While casual Russian uses the zero copula in the present tense, formal Russian requires an explicit verb.
1. Являться + Instrumental:
Used to define a subject's identity or status. It is static and categorical. In formal writing, it is often used to avoid the subject-predicate dash (—) that characterizes the zero copula in definitions. For example, 'He is a citizen' becomes 'Он является гражданином'.
2. Служить + Instrumental:
Used to describe the function or utility of an object or idea. It often answers the question 'What purpose does this fulfill?'. For example, 'This serves as a reminder' becomes 'Это служит напоминанием'.
3. Case Requirement:
Both verbs strictly govern the Instrumental case. You must apply the correct endings (-ом/-ем/-ём for masculine/neuter, -ой/-ей/-ью for feminine, -ами/-ями for plural).
4. Register:
Avoid using these in daily conversation. Saying 'Ты являешься моим другом' (You are my friend) sounds like a legal contract rather than a friendly sentiment.
Examples (4)
- Данный инцидент является грубым нарушением международного права.
This incident constitutes a gross violation of international law.
Word by Word: This incident is a gross violation [Instrumental] of international law.
Here, 'является' defines the legal status of the incident using the Instrumental case for 'нарушением'.
- Результаты эксперимента послужили основой для новой теории.
The results of the experiment served as the basis for a new theory.
Word by Word: Results [of] experiment served [as] basis [Instrumental] for new theory.
The verb 'послужили' (past tense of служить) indicates the functional role the results played.
- Он является единственным наследником этого состояния.
He is the sole heir to this fortune.
Word by Word: He is [the] sole heir [Instrumental] [of] this fortune.
In a legal context, 'является' is used to define his official status as an heir.
- Эта книга служит прекрасным примером классической литературы.
This book serves as a wonderful example of classical literature.
Word by Word: This book serves [as] wonderful example [Instrumental] [of] classical literature.
Using 'служит' highlights the book's function as an illustrative example.
Common Mistakes
Using the Nominative case instead of the Instrumental.
Это является проблема.Это является проблемой.After 'являться' and 'служить', the following noun must always be in the Instrumental case, never the Nominative.
Using 'являться' in casual conversation.
Ты являешься очень добрым человеком.Ты — очень добрый человек.In speech, 'являться' sounds robotic. Use a dash (zero copula) or simply omit the verb.
How It Connects
Learn This First
To learn this pattern, learners must first understand the use of the instrumental case for roles and functions, which is typically first encountered with the verbs 'быть' (to be) and 'стать' (to become). Additionally, learners should be comfortable with basic nominal predicates and standard verb conjugation to correctly apply these formal substitutes in academic or official contexts.
